aborts evaluations running in all parallel subkernels.


AbortKernels
aborts evaluations running in all parallel subkernels.
Details

- AbortKernels[] attempts to put subkernels in a state suitable for new evaluations and verifies communications links to them. Any subkernel that does not respond is removed from the list of available subkernels as given by Kernels[].

Applications (2)
Scheduled evaluations that are no longer needed can be aborted with AbortKernels:
Find such that
is prime, scheduling one search loop for each kernel:
Run them until manually aborted, and clean up by aborting all parallel kernels:
Properties & Relations (2)
ParallelTry is essentially implemented in terms of WaitNext and AbortKernels:
If aborting fails, kernels can often be closed and reopened:
